EDGAR L. KINSLEY, OF CAMBRIDGEPORT, MASSACHUSETTS.

IMPROVEMENT IN AXLE-BOXES FOR VEHICLES.

Specification forming part of Letters Patent No. 146,394, dated January 13, 1874; application tiled November 13, 1873.

Vcation and represented in the accompanying dra-Wings, of which- Figures 1 and 2 are side views, Figs. 3 and 4 end views, and Fig. 5 a longitudinal section, ot' a wheel-box provided with my invention.

The sleeve or part A of the box is to be a wrought-iron tube, terminating at one end in a cylindrical head or enlargement, a, which, at its junction with the tube, has a shoulder, b, all being constructed and arranged as represented. There is combined with such tubular part or sleeve A a cast-metal collar, B, anged at onel end, as shown at c, and provided with wings or tongues d d extended from it, all being as shown. This collar B fits concentrically'upon the sleeve or part A, and rests against the shoulder, the collar, preparatory to being placed upon such part A, being heated so as to expand it, in order that it may be driven thereon, and subsequent-ly, by contraetion while cooling, fit rmly to it.

i In making a common wheel-box in one piece of metal with wings, it has generally to be east in a mold, for to construct it wholly of wroughtiron, andturn and finish it, is an ex pensive and difficult matter. The part A `can be readilyT and expeditiously turned and iinished in a lathe, the east flanged collar being previously or subsequently xed in such part A. In this way I can produce a wheelbox much cheaper than one of like form made wholly of wrought-iron and in one piece, with its flanges or wings.

I do not claim the axle-box described in reissue Patent No. 4,594, dated October 17 ,187 1, and granted to David Dalzell, as such differs in construction materially from my axle-box. In the rst place, it has no head and shoulder to the sleeve, as in my axle -box; and, secondly, it has no collar provided with wings, and driven, in a heated state, on the sleeve, and up to the shoulder thereof, and fixed thereon by contraction induced by reduction of teinperature. In my axle-box I avoid the use of screws to hold the parts together.

I claim as my invention- The axle-box A,1nade with the enlargement a and shoulder b, in combination with the sepa rate cast-metal collar B, having win gs d d, and xed on part A, all substantially as and for the purpose set forth.
